To @ZZ whom t may concern:

Be it known that I, VALERY GALLIEN, manufacturer, acitizen of the Republic of France, and a resident of 10 Boulevard Emile-Angier, Paris, France, have invented certain new anduseful Improvements in the Method of Making Armored Tires;and I do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to the manufacture of pneumatic tires for cycles, motor-vehicles, and the like, consisting of a rubber base having a cover or tread, preferably of leather, ar.- mored or unarmored, securedthereto, and has for its obj ect the method of Securing such protecting-band tothe rubber base so that it will be 'firmly united thereto.

Referring to the drawings, in which like parts are similarly designated, Figure 1 is a cross-section of my improved tire, and Fig. 2 is a plan of part of a tire developed or flattened out. i

I take a. rubber tire d, such as is now made, whether it be ofpure rubber or not, and preferably Well scrape or fur the outer surface With a rasp or .otherwise andthen coat the furred ortion or the surface with a solution of rub er, applying one or more coats, if necessary. A strip of leather f, preferably lchrom-tahned leather, is cleaned of grease by a suitable solvent, such as'benzene. The edges, skived thin or beveled, are also covered with one or more coats of rubber solution, the leather being preferably roughened on its surface. I use chrome-tanned leather because I have found it to bethe only kind of leather that will hold Well when vulcanized to the rubber and that will stand the skidding When rounding curves. I then a ply to the rcontact-surfaces of the coated eather and tire after they are dry and by means of a brush a liquid composed of carbon bisuhid, about ninety-eiuht per cent., and protochlorid of sulfur, about twv per cent. I then ress the surfaces to be united tightly together, thereby obtaining a vulcanization in the cold that causes the parts to adhere firmly together. This strip of leather 'or other substance f rotects the underneath rubber tire d from being chafed or Worn by the inner ends of the armor-rivets c. I then form the armor-band proper, which consists, referably, of a strip of chrome tanned eather t, having thinned or skived edges that reach down the sides of the tire, and rivet it to another strip of leather a, that is directly on the tread of the Wheel.

I preferably use rivets havin a head c and a shank that is split prefera ly by running a milling-tool through the shank to form two portions c2, that are passed through both of the pieces ct and l) and then bent over or clenched on the under side of the piece b. The under side (preferably the flesh side) of the piece b is then cleaned from grease and furred or rou'ghened and coated With rubber solrlriitlion.

e rotectin -stri is similarl re ared or coatld with rbbeipsjblution andrviiheil dry brushed over with the mixture of sulfur compounds above set forth and the parts are pressed together, this method producing a cold vulcanization ofthe arts.

The general use of suc tires on automobiles has demonstrated that the uniting of the leather and rubber is all that is to be desired and that they Wear exceptionally well and the chrome-tannedleather is eculiarly Well adapted to vulcanization in t e cold.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

l. The method of making armored tires which consists in cold-vulcanizing the flesh side of chrome-tanned leather to rubber tires, substantially as set forth.

2. The method of making armored tires which consists in cold-vulcanizing the flesh side of chrome-tanned leather to rubber tires under ressure, substantiallyas set forth.

3. T emethod of making armored tires, which consists'in furring or rudhening the .surface of the rubber tire, similariy preparing both sides of a Charing-strip, coating the prepared surfaces With rubber solution, applylng to the coated proximate surfaces a mixture ofcarbon bisulfid and protochlorid of sulfur, uniting the parts under pressure, unitv in a chrome-tanned leather tread to the haii; si e of a strip of similar leather Wider than the chang-strip, studding the united tread IOO lcarbon bisuld an uniting the parts by presand strip with armor-rivets, roughening the In testimony that' I claim the foregoing as fiesh side of the latte strip, coating it, the my invention Ihave signed my name in preschang-stripand part of the tire beyond the ence of two subscribing Witnesses.

chang-strip with rubber solution, and then VALERY GrALLJLENE with the aforesaid rotochlorid of sulfur and Witnesses:
